Technology moves slowly in aviation. New airplanes are still rolling out using 286 processors and some still get updates via floppy disk.
Way incorrect. Deltamatic is a series of interconnected mainframe computers using the
IBM zTPF operating system. This OS is used by a small number of extremely high transaction processing environments. AMEX, VISA, and several airline and banking systems use this operating system as a central server, usually fronted by "mid-tier" and front end Lintel servers.
